TRAVELER FOR RING-:SPINNING FRAMES.

SPECIFICATION formingpart of Letters Patent No. 478,256, dated July 5,1892.

Application filed March 7, 1892. Serial No. 424,006. (No model.)

To all whom, it may concern: Be it known that I, SAMUEL S. FOWLER, ofElizabeth City, in the county of Pasquotank and State of North Carolina,have invented certain new and useful Improvements in Travelers forRing-Spinning Frames; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention is an improvement in ringtravelers used onspinning-frames, twisters, and like machines. It is intended to remedydefects in travelers as now made and used and give them a level easyposition when running to prevent them from Wearing unevenly. It will befound fully illustrated in the accompanying drawings.

Figure 1 is an enlarged perspective view of one of the travelers. Fig. 2shows an elevation of the inside of half a spinning-ring with animproved traveler on it. Fig. 3 is an elevation of a like portion of aspinning-ring with a traveler such as is generally used. Fig. 4 is anelevation of a like portion of a spinning-ring with a traveler of theusual kind, having one-half of its under projection Worn away, as shownin Fig. 5. Fig. 5 represents the under side of an ordinary traveler,showing the gap in it caused by wear.

One great difficulty that causes much trouble in the use of the commontraveler is the uneven wear on the under side of the traveler, in thatpart that extends in under the rim of the ring I) on the inside to holdthe traveler down on the ring. The tipping of the traveler, resultingfrom the strain of the thread 8 on the front edge at d, Fig. 3, causesthe front corner g to take all the wear from the contact with the underside of the rim of the ring. The result of such wear is a gap 0 made inthat corner, (see Fig. 5,) and in Fig. 4 the position of the travelerrunning on the ring after the gap is worn is shown. As the wearing ofthis gap proceeds this part of the lip presents a thin sharp edge at anangle to the line of the under side of the rim of the ring, that growsmore and more obtuse, and naturally this sharp edge will not slidefreely on the ring, but will-produce an interrupted hitchy motion,especially if there is the slightest variation in the surface of theunder side of the lip of the ring. This unsteady jerking motion as itincreases breaks the thread and otherwise injures it. Myinvention foravoiding this difficulty consists in making a recess 0 in the edge ofthe top part of the traveler. (See Fig.1.) This recess 0 is madeto'extend back nearly to the middle of the bar of the traveler and bringthe upward tension of the thread 8, that draws through it, far enoughback from the front edge of the traveler to hold the traveler up withits under lip in level contact with the under side of the rim of thering b, as shown in Fig. 2. Running in this position the wear on the lipof the traveler will be uniform for its whole length and a traveler willrun in good condition for a much longer time, though the prevention ofthe stoppages because of breaking of the thread and avoiding injury tothe product are of much more consequence than the saving made in cost ofextra travelers.

Having thus described my improvement, I 75 claim as my invention As anew article of manufacture, a ring-traveler for spinning and twistingframes constructed substantially as described-that is, consisting of aflat strip of metal having its ends bent-down and in to hold it on thering and a recess made in one edge on its upper side to allow the threadto draw from near the middle of the top of the traveler, as herein setforth.

S. S. FOWLER.
